APPARATUS FOR TREATING THE HAIR AND SCALP.

Application filed March 12, 1927. Serial No. 174,877.

My invention relates to apparatus for treating the hair and scalp, andthe object of my improvementnis to provide apparatus for warming anddrying the hair and scalp, adapted to treat the entire scalp at oneoperation and to dry the hair in a minimum length of time.

This object I have accomplished by the means which are hereinafterdescribed and claimed, and which are illustrated in the accompanyingdrawings, in which Fig. l is a vertical central section of my improvedapparatus with parts in side elevation, or broken away, and Fig. 2 is ahorizontal section of the funnel-form air conduit taken on the brokenline 2-2 of said Fig. 1 and looking downwardly as indicated by thearrow.

It is to be understood that various modifications of the apparatus shownmay be used while still remaining within the scope of my invention andthe protection of the claims hereof.

My said apparatus is designed for employment in beauty parlors, barbershops, or by individual users.

The apparatus comprises a hollow chamber 1 whose lower part 2 isdownwardly coned, both ends of the chamber 1 -2 being open, the lowerend having an outer circumferential flange 18. The upper end of thechamber has an inturned annular flange on which is fastened bars 3,preferably curved and to which a small electric motor 4 is securedcoaxially with the chamber. On the depending short motor shaft in saidchamber are .fan vanes 5. The numeral 6 denotes'a horizontal part of avertically disposed cylindrical standard 7 whose lower partis slidablyseated in the upper hollow part of a standard 8, and the latter may berelatively fixed, as supported upon any kind of base, whether fixed oradapted to be shifted from one location to another, not shown. A sleeve9 mounted-on the standard 8 is with said standard 8 apertured in linewith an interiorly threaded hole to receive a wing-screw 10 which servesasa set-screw to engage terminally the standard part 7 to hold it in adesired height of elevation.

A pair of electric lamps 12 are mounted in the upper cylindrical part 1of said chamber immediately below the fan 5. A downwardly concavedreflector 15 is supported on an inner bracket 16 on the inner wall ofthe coned part 2 of said chamber about midway of said coned part andhaving its circumhollow air chamber preferably made of some flexible andrelatively air impervious material such as rubberized cloth, and whoseopposite upper and lower open ends have annular elastic insertions-"suchas denoted by the parts 20. The upper elastic ring 20 may be releasablymounted around the lower flange 18 of said chamber 1-2. The lowerelastic ring 20 may encircle elastically the head of a person to betreated so as to inclose the entire hair and scalp, Within the airchamber 19.

Referring to Fig. 2, the numerals 21 and 22 denote spiral segments ofplates which are mounted along the inner wall of the chamber part 2 toterminate below at the lower opening of the part 2, the upper parts ofsaid plates being wider than the lower.

The rotating fan 5, and also the lamps 12 and 15 are controlled by meansof switches 11 set in the sleeve 9.

Air driven centrally downwardly by the fan, is preheated by the upperlamps 12, then impinges upon the convexity of the depending hollow body13 and diverted laterally around the latter to pass downwardly throughthe coned chamber part 2 close to its inner wall. The air then, inpassing against the spiral plates 21 and 22- downwardly, is given bysaid plates a swirling motion or direction which causes the air to moveclosely along the inner coned parts of the chamber part to and bedelivered into the air chamber 19 with the same rotatory movement tolikewise move along the inner,

wall of said chamber 19 spirally until it impinges upon thecircumferential margin of the scalp of the person treated. The arrowsshow the directions taken by said air current in passing both downwardlythrough the chamber 19, and when returned centrally upwardly through thechamber after thoroughly bathing the scalp and penetrating the hair.This causes the air to impingeupon the scalp throughout at abrupt anglesbelow and from thence upwardly in penetrating currents over the scalpand through the hair, rapidly drying all the scalp and hair. The dryingprocess is expedited by the heat rays from the lower lamp 17 reflecteddownwardly by the concave reflector 15, and which rays afi'ect all partsof the scalp and hair. Air returning upwardly through the central spacesof the chambers '19 and-12, is received by the and radiating from thescalp while drying.

This results in a large saving in time and labor in the operation of theapparatus.

l-laving described my invention, what I claim as new, and desire tosecure by Letters Patent, is: l

1. In a device of the character described,

an open ended chamber, means within said chamber for creating a spirallyprogressive current of air while passing under pressure therethroughabutting the inner'wall thereof, a hollow open ended flexible chamberhaving one open end closely mounted upon the open delivery end of thefirst-mentioned chamber, and means for closely adjustingly the otheropen end of the secondmentioned chamber around the head of a person toinclose the scalp within it, and whereb" the second-mentioned chamber isinflate with air under greater than atmos- 2. In a device of thecharacter described w an open ended chamber, means within said chamberfor creatin a spirally progressive current of air therethrough abuttingthe inner wall thereof when air is forced through the chamber underpressure, a flexible open endedv hollow body having one open end mountedabout the open dehvery end of said chamber sealingly, means forelastically fitting and'wcuring releasably the other open end ofsaid-hollow body around the head of a person to inclose the scalpthereof within said body, and heating means within said chamber topreheat the air passing therethrough into said hollow body, the airentering said body inflating it and becoming compressed above thepressure of the atmosv phere.

3. Ina device of the character described, an open ended chamber, meanswithin said chamber for impressing a spiral movement upon air forcedunder pressure through the chamber to cause the air to move along theinner wall of the chamber spirally progres sively, an-open endedflexible air impervlous hollow body having one open end sealed removablyupon the open delivery end 0t said chamber and having at its oppositeend an annular elastic element for adjustingly securing it around thehead of, a wearer to inclose the scalp Within said body, means withinsaid chamber for preheating air passing through it into said hollowbody, a concave reflector mounted in said chamber, and other heatingmeans apposed to the concave face of the reflector whereby the reflectordirects reflected heat rays through said hollow body upon the entirescalp of the person treated.

4. In a device of the character described, an open ended chamber, meansfor driving a current of air therethrough, the delivery part of thechamber being conical, a flexible open ended body having one endremovably elastically fitted upon the coned delivery end of saidchamber, and having its other open end provided with an annular elasticelement to hold it releasably upon and around the head of a persontreated, means mounted within said chamber shaped to impress aprogressive spiral movement on air passing through it and through saidbody, heating means within said chamber for heating air passing throughit, a reflector within said chamber and heating means apposed to thereflecting surface of the reflector to direct heat rays through saidbody upon the whole surface of the scalp of the person treated,

and. a hollow discharge device having an enlarged bell end within thechamber near 105 and of greater diameter than said reflector,

and having a tubular part traversing the wall of the chamber to vent'thereturning air from said hollow body, whereby the air in said hollow bodyis kept at a pressure no greater than atmospheric pressure.

In testimony whereof I aflix my signature.
